Quote from the announcement email:
-------------------------------------------------------
I've just released version 2.2 of the Haskell-mode package for Emacs.
It has very few visible changes, mostly some commands to query an underlying
interactive hugs/ghci in order to get type/info about specific identifiers,
courtesy of Matthew Danish.
It does have some non-trivial changes in the indentation code and various
other minor details. These have seen very little testing until now, so
don't be surprised to find regressions: just complain back to me.
As always, the place to find this package is:
http://www.iro.umontreal.ca/~monnier/elisp/
-------------------------------------------------------
I copied the 2.1 ebuild and replaced the version with 2.2. It works on my
system with emacs-cvs-22.0.93-r2.
However I did get some warnings when compiling the lisp sources:

(Maybe this is because I use a very recent emacs version)
Reproducible: Always
